Why look for an Attachment Project alternative
Attachment Project is a free attachment quiz. Their attachment-theory page says the quiz is based on the ECR. Stay there when a free attachment quiz is the whole job. Look elsewhere when you want the published 36-item ECR-R on its own, a Big Five score with no attachment, or Big Five scores with an attachment overlay and a partner comparison.
Attachment Project vs Deep Personality
Attachment Project is an attachment quiz. Their page says it is an online version of the ECR and that it is free. Deep Personality is a different path: IPIP-50 domain scores, an attachment overlay, and an optional partner comparison after two people finish. We do not administer the 36-item ECR-R. The longer note is Deep Personality vs Attachment Project.
What Deep Personality gives you
Deep Personality runs the IPIP-50: fifty public-domain Goldberg items, ten per domain, five domain scores. Then an attachment overlay: anxiety and avoidance, then a style label. Then an optional partner comparison after two people finish. The overlay is not the 36-item ECR-R. The comparison is not a compatibility percentage.
Deep Personality is free to start: the short quiz is a ten-item IPIP teaser, it is not the IPIP-50, and it does not score attachment.
You can start for free. The short quiz is ten public-domain IPIP items. It is a teaser, it is not the IPIP-50, and it does not score attachment. The full report is paid: Individual is $9.99 per month and includes the attachment overlay. A preview of the written report is available before you pay.
Partner comparison is $14.99 per month. A one-year Comparison gift is $49. Both include the individual report, the attachment overlay, and a partner comparison. Lifetime, at $149 once, includes partner comparison and does not renew.
The free quiz is ten IPIP items. It does not score attachment, and it is not the IPIP-50. The full inventory is the Big Five test. Attachment on this site is the attachment style test. The side-by-side view, after two completers, is the partner comparison. Current prices are on pricing.
